Application June 15, 1931, Serial No. 544,553 7 Claims. (o1. dos-ear This invention relates in generalito a combined .nail and'lock for shingles and has more particular reference to fiexible composition roofing and shingles.

"One of the principal objects of the invention is in the provision of a shingle holding device in which there is no direct hole for leakage through the shingles. r H

A further object of the invention is in the provision of a combined nailand lock for shingles in which the perforations through the shingles and into the roof holding .board are offset to prevent leakage. 1

n; further obj ect of'the invention is in the provision of a combination nail and shingle lock which is bent ordeformed for driving into the roof deck.

Other objects of the invention will appear herematter, a preferred embodiment of the invention being illustrated'in the accompanying drawing.

Figure 8 is a section taken on the line 88 of Figure '7. v

In attaching strip or individual composition shingles to a roof deck it is desirable to prevent the exposed edge or butt from upward movement, but if a fastening nail is inserted directly through the shingle into the roof deck, a direct hole for leakage is provided. With some types of shingles and roofing the fastening nails of one course are covered by the shingles of the course above, but in this type, a separate attaching device is preferably used for holding down the exposed edge or butt of the shingle.

In the present invention, both of these objections are overcome and the fastening nail and the shingle lockare combined in a single device which not only secures the shingles or roofing to the roof deck but also provides a lock extending through or about the exposed edge of the shingle andqout of :line' with the fastening portion so? that nodirect :hold is provided throughladjacent shingle coursesto' provide a direct path for leakage.

Referring now more particularly to the drawing, a number of shingle strips 10,;11, and 12 are 30 applied to boards 13 of aroof deck in overlapping relationand the exposed edges of these strips are usually cut orrecessed to form a shingle pattern having exposed butts or tips 14.

A combined shingle nail andlock :15 composed of stiff wire or the like, is angularly bentqtoprovide a: driving portion 16 whichypreferably has a slightourve or offset; 1'1 adjacent wthebodmportion to strengthen it for driving intothe roof deck. The other end 18 of. the wire isalsouangularly ibent 7.0 taking the position 18o as indicated in; Figure 2, so

that inapplying the overlying shingle ,12; thepoint of this extremity may be inserted through the lower .exposededge of the shingle and thisendlS of qthexwire then bent downwardlyagainstthe 76 upper face of the shingle, asshown in -Figure.2. Ifdesired, axshingle; nail lock 20wmay-have an extremity 2-1 for insertion through the-exposed edge of a shingle .12 withtthe otherextremity ,22

partially-bent -so?that= it will passreadil-y through 1 the softer material,ofthecornposition shingles-but when it engages the boards 13 of the roof deck it will curl upwardly thereby securing the different strips tightly together and preventing their dislocation from each other but not actually securing the shingles to the deck.

Another form of shingle nail lock 25 is shown by Figure 4 having a pointed extremity 26 adapted to be inserted through the shingle layers into a roof board 13 and having a driving oifset 27 at the head of the pointed extremity 26 and with a locking extremity 28 adapted to extend around the lower edge of a shingle 12 and not through it, with a tip 29 bendable downwardly against the surface of the overlying shingle 12 out of direct 9 line or offset with respect to the driving portion 26. A similar nail lock 30, as shown in Figures 5 and 6, has a driving extremity 31 connected to the main body by a lateral extension or offset 32 and with a driving bend at the head of the driving 1 portion and with an overlying extremity 34 having a downwardly turned tip 35. With this construction, the driving end 31, being offset, is easily engaged by a hammer or other means for driving it into the roof deck. 1 A strip device for accomplishing the same result is shown by Figures '7 and 8, in which a metal strip 36 has oppositely extending pointed tongues 37 and 38 punched out of the strip on opposite sides thereof and of sufficient length so that one of the tongues may be inserted through one or more layers of composition shingles into a roof deck and the other tongue may be inserted through the exposed edge of an overlying shingle strip and thereafter bent over for attaching and holding the shingle strip in place.

With these combination shingle nail and lock devices, it is obvious that the overlying shingle or shingle strip may be secured in place by inserting a portion of the device through the strip or around the edge of the strip and thereafter clinching the device in engagement with the shingle; neither the portion perforating the overlying shingle nor the extremity of the device is in alignment with the nailing end of the look so that no direct hole is provided by means of which water may pass through the layers of shingles and into the roof deck. The perforations are offset to prevent leakage and the perforation of the overlying shingle strip or the point of engage- ,,ment of the shingle nail lock with the surface of this stripis below the point of attachment of the device to the roof deck so that even if water did pass through the outermost shingle it would not run into the hole made by the driving part of the nail lock. It is furthermore obvious that this combined nail lock may be placed at the very tip of a shingle butt or through it, or may extend over the edge of the shingle at an angle thereto, all as shown in Figure l.

I claim:

1. A wire shingle nail lock having a shingle perforating portion, a nailing portion, and a connecting portion, and the nailing portion having a stiffening crook adjacent but below the top to facilitate driving it without bending.

2. A combined wire nail and shingle lock comprising a continuous round wire stock having a nailing portion at one end having means for stiffening it for driving, a bendable shingle perforating and engaging portion at the other end, and an intermediate connecting portion to offset the other portions so that the engaging portion is not in line with the nailing portion, the stiffening means comprising an offset in the shank of the nailing portion below the top thereof.

3. A combined nail and shingle lock comprising a nailing portion having a stiffening driving offset at the top and in the shank thereof adapted to be inserted through a lower shingle course to attach shingles to a roof deck, a locking portion extending at an angle to the nailing portion and adapted to be inserted through and bent into engagement with the surface of a shingle in a course to cover the upper end of the nailing portion and the locking portion extending out of line with the nailing portion to prevent formation of a continuous hole through adjacent shingle courses.

4. A combined nail and shingle lock formed of continuous round wire stock, the ends being bent one to form a nailing portion having a shank with a top stifiening crook and having barbstherein, and the other to extend through and over the top of a shingle layer in a course above the nailing portion and having an extremity bendable to engage the upper surface of such shingle layer but out of line with the nailing portion below.

5. A shingle nail lock having a nailing portion with a shank having an oiTset adjacent but below the top for stiffening it for driving, a bendable shingle perforating and locking portion, and an intermediate connecting portion for offsetting the other portions laterally and out of alignment with each other.

6. A wire nail and shingle lock having a barbed nailing portion at one end with a shank having an oifset stiffening crook adjacent but below the driving end, a bendable shingle perforating portion with a shingle engaging tip at the other end, and a connecting angular portion to offset the other portions so the tip and nailing portion are not in alignment.

7. In a shingle nail and look made of continuous bendable round wire stock, an extremity bendable to engage a shingle, an intermediately connecting portion, and a driving extremity at an angle to the connecting portion having an offsetting crook in the shank at its upper end but below said angle adapting this extremity to be driven without easily bending.
